polyethylene glycols

Polyethylene glycol is a medication that is used in the management and treatment of constipation. It is in the laxative class of drugs. This activity describes the indications, action, and contraindications for polyethylene glycol as a valuable agent in the trePolyethylene glycol is a polymer with the chemical formula HO (CH2CH2O)nH, non-irritating, slightly bitter taste, good water solubility and good compatibility with many organic components. It has excellent lubricity, moistening, dispersion, adhesion, can be used as an antistatic agent and plasticizer, and has a wide range of applications in cosmetics, pharmaceuticals, chemical fibers, rubber, plastics, paper making, paint, electroplating, pesticides , metal processing and food industry.
1. Polyethylene glycol series products can be used in pharmaceutical. Low relative molecular weight polyethylene glycol can be used as a solvent, co-solvent, O/W emulsifier and stabilizer, used to make cement suspensions, emulsions, injections, etc., and also as water soluble ointments matrix and suppositories matrix, Solid waxy high molecular weight polyethylene glycol is widely used to increase the viscosity and solidification of low molecular weight liquid PEG as well as to compensate for other drugs; For drugs that are not easily soluble in water, this product can be used as a solid dispersant carrier to achieve the purpose of solid dispersion. PEG4000, PEG6000 is a good coating material, hydrophilic polishing materials, film and capsule materials, plasticizer, lubricant and drop pill matrix for producing tablets, pills, capsules, micro encapsulations etc.

2.PEG4000 and PEG6000 are used as excipients in the pharmaceutical industry to produce suppositories and ointments; It is used as a finishing agent in the paper industry to increase the gloss and smoothness of paper; In the rubber industry, as an additive, it increases the lubricity and plasticity of rubber products. Reduces power consumption during processing and extends the life of rubber products.

(3) Polyethylene glycol series products can be used as raw materials for ester surfactants.

4.PEG-200 can be used as a medium for organic synthesis and a heat transfer medium with high requirements, and is used as a moisturizer, inorganic salt solubilizer and viscosity adjuster in daily chemical industry; Used as a softener and antistatic agent in the textile industry; It is used as a wetting agent in the paper and pesticide industries.

5.PEG-400, PEG-600, PEG-800 are used as substrates for medicine and cosmetics, lubricants and wetting agents for rubber industry and textile industry. PEG-600 is added to the electrolyte in the metal industry to enhance the grinding effect and improve the shine of the metal surface.

6.PEG-1000, PEG-1500 is used as matrix or lubricant and plasticizer in pharmaceutical, textile and cosmetics industries; Used as a dispersant in the coating industry; Improve the water dispersibility and flexibility of the resin, the dosage is 20~30%; the ink can improve the solubility of the dye and reduce its volatility, which is particularly suitable in wax paper and inks cushion ink, and can also be used in ballpoint pen ink to adjust the inks viscosity; In the rubber industry, as a dispersant, promote vulcanization, which is used as a dispersant for carbon black filler.

7.PEG-2000, PEG-3000 are used as metal processing casting agents, metal wire drawing, stamping or forming lubricants and cutting fluids, grinding cutting fluids and polishes, welding agents, etc.; It is used as a lubricant in the paper industry etc. And is also used as a hot melt adhesive to increase rapid rewetting capacity.

8.PEG-4000 and PEG-6000 are used as substrates in the production of pharmaceutical and cosmetic industries, playing the role of adjusting viscosity and melting point; It is used as a lubricant and coolant in the rubber and metal processing industries and as a dispersant and emulsifier in the production of pesticides and pigments; used as anti static agent, lubricant etc. in textile industry.

9.PEG8000 is used as a matrix in pharmaceutical and cosmetic industries to adjust viscosity and melting point. It is used as a lubricant and coolant in the rubber and metal processing industries and as a dispersant and emulsifier in the production of pesticides and pigments. Used as an antistatic agent, lubricant, etc. in the textile industry.atment of constipation
